Optimum Time's Jumbo Timer just got better.

Huge Dot Matrix Display
The display is huge - 38mm in diameter. This makes the watch much easier to read and allows for the countdown time and real time to be displayed simultaneously (perfect for Race Officers). There is an option for massive digits (23mm high!) in the final 59 seconds of the countdown - just take a look at the product images. There will be no problems reading the time in the hectic final minute before the start.

Vibration Alarm
During the start countdown, the watch will vibrate in conjunction with the audible alarm. This is an invaluable feature if you are unable to see or hear the watch - perfect for those really windy days or when you're jostling for position on the start line in a big fleet. The vibration feature can be disabled if you desire.

Rechargeable Battery via USB
No more opening up your watch to replace the battery and potentially compromising its water proof integrity. The battery will last for at least 700 start sequences with the vibration feature active - it will last even longer if this feature is disabled. When battery power is low, a warning will flash on the display.

Other features include:

• Shock Resistant Construction
• Water Resistant to 5 ATM (50 metres)
• Normal time keeping mode

The sailing countdown can be programmed in 1, 3, or 5 minute increments, and then set to repeat or count up. The sync button is the most important feature of the watch, it allows you to snychronise your countdown to the next minute - an invaluable tool if you start the countdown late.
